I have one node kerberos setup. I am able to query kdc using kadmin.local but when I try querying using kadmin( kadmin -p admin/admin@xxx.xxx.xxx) it fails with error:

kadmin: Communication failure with server while initializing kadmin interface
Kerberos services are running fine.

I have started the kerberos services using command: /etc/init.d/krb5-admin-server start
krb5.conf
[realms]
    xxx.xxx.xxx = {
            kdc = devkdc.xxx.xxx
            admin_server = devkdc.xxx.xxx
Kerberos admin works on port 749 by default. Make sure that is opened and can be accessed from the client hosts.
